Resistor wani ɓangare ne a cikin da'irar lantarki wanda ke sarrafa adadin wutar lantarki . Resistor da ake amfani da su a da'irar lantarki yawanci suna da siffar silinda tare da waya a ƙarshen biyu. Ana nuna ƙimar juriyar resistor ta lambar launi kuma ana nuna ta a saman resistor ɗin.
Ana iya tantance ƙimar juriyar resistor ta hanyar fassara lambar launi ta resistor . Don fahimtar wannan, da farko bincika teburin da ke ƙasa, sannan a yi nazarin matsalar misali don tantance ƙimar juriyar resistor.
Misali tambaya ta 1:
Darajar juriyar resistor a hoton da ke gefe ita ce...
Tattaunawa
Launuka biyu na farko suna wakiltar lambobi biyu na farko na ƙimar juriya, launi na uku yana wakiltar ƙarfin goma da ake amfani da su don ninkawa kuma launi na huɗu yana wakiltar haƙurin karkacewa.
Launin farko = ja = 2
Launi na biyu = lemu = 3
Launi na uku = launin ruwan kasa = 101 = 10
Launi na huɗu = zinariya = 5%
Darajar juriyar juriyar ita ce 230 Ω tare da karkacewar 5% x 230 Ω = 11,5 Ω. Idan akwai canji a yanayin zafi, mafi ƙarancin juriya shine 230 Ω – 11,5 Ω = 218,5 Ω kuma matsakaicin juriya shine 230 Ω + 11,5 Ω = 241,5 Ω
Misali tambaya ta 2:
Menene ƙimar juriyar resistor a hoton da ke gefe?
Tattaunawa
Launin farko = launin ruwan kasa = 1
Launi na biyu = baƙi = 0
Launi na uku = shuɗi = 106 = 1000.000
Launi na huɗu = zinariya = 5%
Darajar juriyar juriyar ita ce 10.000.000 Ω tare da karkacewar 5% x 10.000.000 Ω = 500.000 Ω. Idan akwai canji a zafin jiki to mafi ƙarancin juriya shine 10.000.000 Ω – 500.000 Ω = 9.500.000 Ω kuma matsakaicin juriya shine 10.000.000 Ω + 500.000 Ω = 10.500.000 Ω.
